To all whom it may concern:

snramron mnx non vacuum CLEANING SYSTEMS.

Be it known that I, CARL R. GREEN, a citizen of. the United States,Dayton, in the county of Montgomery and State of'Ohio, have inventedcertain new and useful Improvements in Separator- Tanks for VacuumCleaningSystems, of

which the following is a specification.

My invention relates to improvements in vacuum cleaning apparatus andparticularly to receiver or separator tanks therefor.

The object of the invention is to greatly simplify the construction aswell as the -me'ans and mode of operation of such devices whereby theywill not only be cheapened in construction, but will be more eflicientin operation and unlikely to get out of repair. v

With the above primary andvother incidental objects in View as willappear from the specification, the invention consists of the means,mechanism, construction, and mode of operation or their equivalentshereinafter described, and set forth in the claims.

In the drawings Figure l is a vertical sectional view of the assembledtank. Fig. 2 is a transverse'sectional view on line w-m of Fig. 1. Fig.3 is a bottom planview -of the tank or separator, and Fig. 4 is asomewhat diagrammatic view showing'the relation of the separator tank tothe other parts of the cleaning. apparatus. 1

Like parts are indicated by similar characters of reference throughoutthe several views. 6

The purpose. of the device is to form a receiver for the dirt and dusttaken up in the cleaning operation, and to separate the] dust from thecurrent of air in its passage through the tank. l

The tank proper comprises two members an upper portion 1 and a lowerportion 2 provided respectively with-peripheral {flanges nected. Thelower portion 2 'is preferably formed slightl conical as shown, and

"is provided with a c osure 5. An inlet nozzle 6 is located in the lowerportion 2 which nozzle is connected with the cleanin device or handpiece 7, see Fig. 4-. An 0 .take 8- leads from the upper portion 1 ofthe tank.

; Secured within the tank and intermediate the inlet 6 and outlet {8 isan'inverted sack 9 of fabric 'orother porous material, through which.the air must pass in'its course from residing at ortions are con-'Specification of Ile tters Patent. 7 Patented Feb, 21., 1911,Application filed February 8, 1908.

the intake 6 to the outlet 8. The sack 9 1 serves to filter the air, thedust particles being deposited on the interiorof the sack, the airpassing through the ,porouswalls and out through the outlet 8 to thepump 10. The sack 9 is made with a laterally projecting brim 11 offabric, somewhat in the form of a peripheral flange about the mouththereof. The diameter of the sack 9 is somwhat less than that of thetank. The sack is secured in position by the engagement of the lateralbrim 11 thereof between the flanges 3 and 4. 1

To maintain the sack 9 central in the tank and to prevent the wallsthereof from comthe sack is in an inflated condition, and thus reducingthe filtering surface of the sack, a metal collar 12 is provided theinterior diaineter of which is less than thatof the tank andsubstantially equal to that of the sack. The inner edge of the collar isprovided with a head 13 ,upon which the sack bears, thus obviatingdanger of chafing or undue wear upon the sack material. The collar 12rests on the brimll of the sack 9 and between the flanges and 4; Packing14 is also inserted between the flanges, and the sack, the collar 12 andthe packing 14 all clamped in position by bolts or rivets 15 connectingthe flanges 3 and 4i 7 Supported on arms 16 in the ortion 2 of the tank,and in direct line with the discharge of the intake 6 is a deflector 17conical in form and, adapted to arrest and distribute the inrushingcurrent of air, permitting the particles of dirt carried thereby tosettle in the bottom of the portion 2.

It has been found in practice that without the use of the deflector 17the inrushing current of dirt laden air will continually agitate thedirt deposited in the bottom of the tank and keep the dirt in violentmotion within the tank, and an undue amount of the larger particleswillbe deposited on' the interior of the sack 9, thus clogging thefilter. The deflector 17 being in direct line of the incoming aircurrent will receive the impact thereof and arrest the current of air,and the dirt carried thereby will settle into the bottom of the tankwhere it will be protected by the deflector 17. V

In order that the deposit of dirt may be readily removed from thetank,the closure 5 is removable and comprises a plate, secured in position bydogs 18 pivoted to ears 19 on said closure plate 5 and engaging a flange20 about the mouth of the tank. The dogs 18 each have'an arm 21 engagingover the flange 20 and an arm 22 having therein an adjusting screw 23bearing on the closure plate 5, whereby the operation of the screws 23will oscillate the dogs 18 on their pivots and cause the arms 21 to bearon'the flange 20, drawing the plate 5 into close contact with the mouthof the tank. The dogs 18 each have twoinward projecting arms 21, 22. Thearm 21 projects over the upper side of the cover plate to a limitedextent, and when in place over the flange. The lower arm 22 projectsunder the cover plate. In

other words, each dog 18 has on its inner side a recess within which thecover plateand flange project, or the dogs might be said to besubstantially 7 shaped, one arm of the 7 being short and engaging on theupper side of the flange 20, the long arm extending below the coverplate. The screws 23 are screwthreaded in the arm 22 and bear upon thecover plate. By operatin the screws 23 the long arm of the dog is orcedaway from the cover plate, but the dog turning on the pivotal connectionwith the cars 19 and causing the short arm 21 to bear strongly on theflange 20 will draw the cover plate more closely to the receptacle by aprying movement in which the dog 18 is a lever, the short arm 21 on theflange being the fulcrum, the. screw 23 in the long arm the power andthe cover plate engaged through the ears 19 the work.

Attached to the interior of the sack 9 is a rod 24 which is suspendedfrom the top thereof when the sack is inflated by the air passing therethrough, but when. the sack is collapsed the rod 24 will drop downwithin reach when the closure 5 is removed and may be used to shake thesack 9 to loosen the particles of dust adhering thereto.

The tank is located between the pump 10 and the hand piece. 7, beingconnected to the pump 10 by the ofl take 8. A conduit 25 connects thehand piece -7 with the intake 6. The pump being operated draws a currentof air from the hand piece 7 through the tank to said pump. The currentof dirt laden air enters the tank through the inlet 6 and is dischargeddownward, striking the deflector 17 by which it is arrested, the dirtparticles being allowed to settle into the bottom of the tank, while theair with some of the more fine dust particles pass upward within thesack 9, the air passing through the porous walls of said sack, and thedust particles being deposited on the interior thereof. The air passesfrom the tank through the outlet 8 to the pump. To remove the dirtdeposit the closure 5 is removed by loosening the screws 23 when the Idogs 18 may readily be disengaged from the flange 20, permitting thedirt to drop from the tank. The rod 25, which will project through themouth of the tank when the tank is open may be shaken-to free the filtersack 9 of any dust particles clingin' thereto, and upon the replacementof the closure 5 the device is in condition for further operation. v H

From the above description it will be ap-' parent that there is thusproduced a device of the character described, possessing the particularfeatures of advantage before enumerated is susceptible of modificationin its form, proportion, detail construction, and arrangement of partswithout departing from the principle involved or sacrificing any of itsadvantages.

Having thus described my invention, I claim V 1.
